Node-restrict 介绍
Node-restrict 能够阻止应用程序使用 procss.binding(‘process_wrap’), process.kill 和
child_process 的 Nodejs 模块。
代码示例：
var restrict = require('restrict');
// ls is whitelisted
restrict({
'whitelist': ['ls'],
'whitelistPath': ['/bin']
});
//set whitelist can be invoked, if the whitelist is dynamic
restrict.setWhitelist(['grep'], ['/bin', '/usr/bin']);
var child_process = require('child_process');
try {
// ls is whitelisted. So you can see the output of ls
child_process.exec('/bin/ls', function (err, stdout, stderr) {
console.log(stdout);
});
// grep is not whitelisted. Exception thrown
child_process.spawn('grep', ['ssh']);
} catch (e) {
//this will throw an error
//[Error: Function call spawn() is prohibited in this environment.]
console.log(e);
}
try {
process.kill(30);
} catch (e) {
//this will throw an error
//[Error: Function call process.kill() is prohibited in this environment.]
console.log(e);
}
